Two Pawtucket Red Sox who have joined the organization as minor league free agents in the past 12 months, first baseman/outfielder Chris Marrero (pictured) and right-handed pitcher Sean O’Sullivan, will represent the International League at the Triple-A All-Star game on July 13 in Charlotte, North Carolina.

Marrero, who is cousins with the system's 17th-ranked prospect on the SoxProspects.com rankings, shortstop Deven Marrero, signed with the organization as a minor league free agent last August and re-upped during the offseason. He has been Pawtucket's best hitter this year, leading the club in hits, home runs, runs, and RBI. His slash line of .278/.334/.467 has him on pace for his best OPS season since 2011, when he was a prospect in the Washington Nationals system. Marrero was named SoxProspects.com Player of the Week in the first week of May, and 2016 marks his fourth selection to a minor league all-star team. He spent most of his career, from 2006-2013, in the Nationals organization, then had short stints with the Orioles and White Sox organizations before signing with the Red Sox. He has played in 39 career major league games--those coming in 2011 and 2013--notching 133 plate appearances and hitting .232/.256/.272.

O’Sullivan began 2015 in the Phillies rotation to struggled to stay there and landed in the Boston organization as a minor league free agent during the offseason. He has done well to make his case to get back to the majors, pitching to a 6-2 record and 2.79 ERA. He has excelled at limiting damage, walking only 10 and allowing just two home runs in 71 innings. O’Sullivan received a brief call-up to Boston, but did not fare as well against big league lineups, surrendering 10 earned runs in 11 innings across three games. After being drafted by the Angels, O'Sullivan has spent time in the Royals, Blue Jays, Padres, and Phillies organizations before joining the Red Sox, and he has 313 major league innings to his credit spread across all of those clubs but the Blue Jays, going 12-23 with a 6.03 ERA.
